The treatment of neuropathic pain ist still a challenge. A new promising therapy is the use
of capsaicin on skin.
The investigators first experiences with capsaicin in patients with peripheral nerve injury
showed changes in the sensibility, which achieved its maximal extent after four weeks and was
regressive, but not completely abolished 1,5 months after application.
In this study the investigators hope to specify, how long and in which way exactly this
changes in sensibility appear.
